On Thursday, a day after House Speaker Nancy Pelosi told President Donald Trump he should delay his State of the Union speech amid the government shutdown, the president grounded the military aircraft that Pelosi and a Congressional delegation were to use to visit American troops in Afghanistan.

Trump, also citing the government shutdown, emphasized that taking a trip while 800,000 federal workers weren't getting paid is "totally inappropriate," he wrote to Pelosi in a letter.

Those rules, however, didn't apply to his wife, first lady Melania Trump, reports say.

@CivMilAir, a Twitter account that tracks "rare/interesting" air traffic, posted screenshots of the first lady's plane trajectory. In a thread, the account confirmed that she landed at Palm Beach International Airport after departing from Joint Base Andrews near Washington, D.C.. at around 4:30 p.m. Thursday.

According to the Palm Beach Post, Air Force One was spotted on the airport's tarmac.

CNN White House correspondent Abby Philip also posted on social media that the first lady had landed in Florida to spend the holiday weekend at Mar-a-Lago.
